Specification of Letters Patent.

Patented June 5, reen.

To all whom, 'ibm/wy concern.-

Be it known that We, ADDISON T. SAUN- DERs and GEORGE H. SAUND'ERS, citizens of theUnited States, residing at Akron, in the `county of Summit and Statel offOhio,.have invented ,certain new and u'seful Improvements in Ball-Windin Machines, of which the following is a spec'A cation.

OurJ invention relates to machines for Winding playin fballs-that is, to machines which are emp oyed in the manufacture of various kinds of playing-balls which possess as an element of their construction a layer of thread or the like Wound thereon.

Our invention has been desi ned more particularly for use in the manufacture of golfballs havin apart ofthe body portion composed of adayer of iibrous material formed by a series of'windings of yarn or threadinterla-id With `an ladhesive substance; but it Will be evident from the'subsequentdescription of our invention that the main features thereof are equally applicable in applying a layer of Wound yarn or thread to other kinds of playing-balls, such as baseballs,handballs-, tennis-balls, &c.

Our invention has for its primary object toI provide-a simple and eflicient machine which shall eHect auniform and'even Winding ofthe ball in such a manner as to avoid parallelism and insure its sphericity during all stages of the Winding, other minor objects of the invention being to effect the simultaneous ap,

plication of an adhesive substance during the Winding operation, and to effect the auto-f' Amatic stopping of each Winder (Wherefa group of the latterl are arranged to be. dijer-A ated from a single drivingl-shaft) when the vvound ball has attaine e desired dimenslons. f

lStill other minory objects of the invention Will ,appear in connection ,with the subjoined description .of the mechanism.

, To these ends our invention consists in a Winding-machine for .the purposes stated,

. characterized by thenovel features of construction and operation substantially' as hereinafter described and more particularly pointed out in the claims. y

Referring to the accompanying drawings, which illustrate the principle of our invention in the best form in Which We have' as yete em, bodied the same, Fi re 1 is a side elevae tional view with certain portions of the frame and other parts in vertical section of .our improved machine. Fig. 2 is a front `elevaifi. :.3

Fig. 3 is a top plan vieW With certain upper parts Vof the machine removed for the sake of clearne'ss. Fig. 4 is a detail -vieW of a catchl mechanism controlling the'automatic stopping ofthe machine and its actuating device.l Fig. 5 is 'a detail plan vieW'ofa roller Wljich ism operatm upon the thread in its assage from the de ivery-spool to the .bal being Wound. Figs. 7 and 8 are plan and side elevational detail views, enlarged, of a modified type of the catchoperating devices. Flg. 9

is a detail vertical section through a part of the mechanism shown in Fig-.8. Fi 10is a view similar to Fig. 4, illustrating t e catch mechanism in.its idleA or inactive position. Figs. 11 and 12 illustrate in end view and lonitudinal section, respectively, a mechanical eed .device for the adhesive substance that may be employed.

Referring to the dravyings, 1() deslgnates a main driving-shaft around and above Which there may be grouped a series of Winders, all

11 of a pair of Winding on tumbling disks 12,

Whichabut against a iixed collar 13 on one side thereof, and on theiropposite side are provided With al lateral extension 11a of the hub terminating in a clutch member 2f1, as hereinafter more 1particularly described.

.'llhesel .disks which Aconstitute functionally one ofthe principal elements of the machine, are preferably peripherally toothed orjserroo rated, as best shown in Fig. 1,* and have their peripherall portionsvaried 1nl dlstance from the center and bent into wavy and irre u lar formationlaterally, so as to effect a tum lm of the ball -supportedron thelr eriphera .edges as itis bein Wound, but Wit out moving the ball .bod' y in any direction to any To describe these disks ITOA tions are bent outward and the lower portions inward on each disk; also where one disk is bent outward itsmate is bent inward at the location of the ball is maintained approxilmately constant in space,- while its axis of rotation is constantly altering.

Rotatably. mounted in a air of longitudinal supports disposed paral el with the main shaft 10,`o`ne 'of which supports is shown at 14, is a shaft 15, disposed transversely of and above the main shaft 10. This shaft at one end'bears a sleeve 16, having a transverse operating-handle 17 and a collar 18 on its inner end, which collar is notched, as shown at 19, Fig. 4, to accommodate an arm 20, rigid with and disposed radially of the shaft 15. The shaft 15 at a point directly above the shaft 10 carries a depending clutch-operating fork 21, the arms of which embrace and actuatea sleeve 22, that is splined on the shaft 10 and carries atene end a clutch member 23,

adapted to be thrown into and out of driving engagement with the comp anion clutch-member 24, carried by the lateral extension 11HL of the'disk-hub 11, a collar`25 adjustably Xed 4on the shaft 10, as'by a set-screw 26, constituting la stop lfor the slidable clutch member to limit its disenga in movement. Surrounding the transverse 51a t 15 between the fork21 and thesupport 14 is a torsions ring 27, one end of which is secured to the s 'aft through a collar 27, while the other end i is secured to the support 14; The tendenc of this spring is to turn and maintain the sha t vvin a .position in which the shaft-actuating handle 17 is `si'ibstantially horizontal, as shown in the detail view, Fig. 10. Before andduring the winding operation the shaft 15 is'maintained against the action of the 1 sprin 27 in a position wherein the handle 17 is inc ined, as shown in Figs. 1 and 4^, to kee the clutch members in engagement, throug a^"novel catch mechanism automatically rescribedQl y l28, designates ahorizontal sup ort disposed 'transversely of and in front of tliie winding or tumbling disks 12, and having pivotally supiported on its upper surface,` 'as indicated at ,inner ends with blades '31,

leased' by ball-gaging devices, nexttobe de- 29, apair of caliper-arms 30 provided at their isposed in vertical lanes and ccup ing asubstantially par- `alle relation to eachother throu hout the winding operation. The rear en s ofthe caliper-arms 30, behind the pivot `29, yare ver- 6o ticallyapertured to permitf the movement ktherethrough of the rear vertical end portion of a bent U-shaped tripper-rod 32, the inner and longerjvertical member of which passes 'through an aperture in the-underlying support23 and constitutes the pivotal axisof underlymg portion of said tripper is surrounded by a coiled compression-spring 34,

acting between the under side of the support 28 and a head or nut 35 on the lower end of the tripper-rod 32, thereby tending to draw the latter downwardly relatively to the caliper-'arms and the support 28. That vertical member of the tri per which passes through the apertures inLt e rear endsl of the caliperarms has a shoulder 32, adapted to enga e and overlie one margin of the aperture in t e upper caliperar m,'as clearly shown in Fig.`4 and the said apertures are so positioned an related to eachother as to be automatically brought into perfect registration and coincidence when t spread apart by the growing ball as the winding roceeds to a dlstance equal to the desire diameter of the wound portion of the ball, the result of such registration of the a e caliper-blades 31 havebeen ertures being to release the engagement of t e shoulder 32a withthe margin of the upper aperture, and permit the tripper to be drawn by the action of the spring 34 throu h said apertures, as shown in Fig. 10, for t e purpose next to be described.

36 designates' a lever pivotally mounted at 37 .in a suitable support 38 ofthe machineframe, said lever having the end of its longer arm underlying and contactingthe lower end of the shou dered member of the tri per 32,A while pivotally hung from the end 'of its other arm is a link 37, connected, through a pin 38 and slot 39, with'the face of the collar 18.

AThe upper end of the arm 2 0 is forked and has pivotally mounted therein a counterweighted catch-piece 40, said catch-plece being' provided directly above its pivotal point with a notch forming a vertical lshoulder 41',

IOO

which when the catch mechanism is set in 4its y 42 designates a delicate bow-spring connecting the caliper-arms 30 and oeringfa;

light resistance'to their separation. Since iti-"Q1" is desirable that the ball shall not contact] with the two blades 31 of the caliper-arms 30 until. it approaches its full size, said arms are tig set at such avwidth that the ball does notill the space between them until it has yalinost reached its-full size.

43 designates-a shaft. disposed below and 1n mounted a spool of thread or yarn 14,- the '.ree Vend of which is carried.upand lguided througha Ybent wire guide 45 around a ten-` sion-drum 52 hereinafter described, through an eye 16, (open for convenience in threading,)to the-.ba1l-47, which ball is supported front of the disks 12, on which -is loosely v y vx25 I upon and between the peripheries of the wind- A ing and tumbling disks 12 in such Na position .Iso

`on an axle 48, W -ch is slidably mounted in bearings on a pair -f arms 48, Itlturiis freel A on the rod 48a, constituting its axle,

and as considerableI endshake or play ithereon. The roller 49, as shown in Fig. 2, is

mounted on a rod or axle 49a, constituting a horizontally-bent.extension of an arm 49h,

p ivotally supported from a lug on the under side of the tank or vessel 60. The roller 49 lturns freely on its axle and also has considerable free end shake or movement, this characteristic oi" the mountin ofthe rollers 48 and 49 permitting of the ee turning of the ball in various directions conformabl to the impulse given by the disks. The rol er 49 is lightly pressed upon the ball through the agenc of a spring 49, acting upon the lower end o an arin 49 connected to the pivot of the arm 491. A spring-catch 49, attached to the base of tank 60, engages and holds the arm 49b when the upper roller 49 is lifted, as when changing balls, being disengaged therefrom by simpl pulling or pressing down on the arm 49b W en the roller is to be let down on a new ball. i

50 designates a counterweighted lever pivl otally mounted on' a. shaft 51 beneath the machine and bearing with adjustable friction contact against the spool 44 to prevent the spool of thread or yarn from `running 4too freely or when the Winder stops. 'A similar sprin -pressed brake 12 acts on the periphery o hub 11 to vprevent running on of disks 12 when thrown out of gear. e

The tensiondevice hereinabove referred to and shown in detail in Fig. 6 consists, essentially, of a short spool or drum 52, having end anges 53 and .mounted by its axle at one end on asupporting-arin 54, the other end being free in order to allow the thread to be more easily carried over the spool. Thesupporting-arm 54 may be attached to the frame of ing-arm 54 and pressed upon .one v,of the i flangia@ by a spring 'or weight, preferably the u er, as, shown at 57, whichgweight may be adjustabl attached tofthearm by au setscrew58' to a ow of Varying' its position along the arm, and thus adjusting the terision.4 It

is evident that thebearing ofthe brake on lthe peripheryof the ange affords a uniform vand evene resistance to the turning of the `bent to form parallel -livery occasioned tally at rivht angles to t drum and -just below it. tached to the framework ofthe machine, extends inward therefrom,"v and its office is to direct the thread to the center or atleast the face of the drum and to keep its direction thereon constant against the variations in dety the unwinding of the fhrealcll from the various parts of the spools en t he machine as thus far described is practically complete for the purposes of eifecting the Winding of the thread u on the ball. the manufacture of many p aying-balls having a layer of wound thread or yarn it is de-y ,sirable to eect the winding in connection with thel aplplication of an adhesive substance to unite t e overlying threads more permanently and solidly and sometimes, also, 1n connection with the application of a Weightrgiving substance, to secure 'the proper specific gravit of the finished article. v

In t e application of our-invention to the manufacture of golf-balls We contemplate the em loyment of such auxiliar and wil next describe a simple an ,eificie'nt -mechanism which we have successfully employed for thispurpos'e. OnA a horizontal sup ort 59, disposed above and transversely of t e winding and tumbling disk l2 .restsA a tank or vessel 60, provided with a lid 61 and uideslyinglhorizone axis of the tension- The guide is at- 8ol l 9o devices -l means', as a yoke 62 and screw 63, for securelyV A l fastening the lid upon the tank to effect a tight closure against the resistance of internal pressure. ThetankOisfurtherrovidedwith a nozzle 64, having a control ing-cock' l 65, from, which nozzle a depending flexible hose 66 conducts the material contained in` the pipe 69 with the interior ofV the valve-box 68 is controlled by a puppet-valve 70, andan rie air-exhaust aperture from the valve-casing` 68 is similarly controlled by a puppet-valve 71. The stems of said puppet-valves ZOVand' 71-both'extend across the chamberofthe valve-casing and are connected for simultaneous operation by an intermediate pivoted -lever 72. i The stem of the valve? 1- extends below and outside of-the'valve-casiri andinas an extension 73, which is transverse y slotted at its lowei` end to receive the outer-'end of an arm 74, projecting from the shaft 1535.- I

'From theforegoing it will be seen-thatwhen the parts are in the relative positions shown in-Figs. 1 andf2 thefdompressed air k from the `reservoir isv passing through Ypipe,v

69, aroundl the valve 7 O'and its-1 sifif'pp'o rting-` stem-into the 'chamber of thecasing `=618,.-and5 from thence around thefsteml of the v"`alve 1 'i 3o into the pipe 67, while whenrthevalve 71 is ber, and the exhaust-opening controlled byvalvef71. l

In some instances where the compound used is not of an easily-iiowing consistency or is more or less lumpy in character it is liable to clog the discharge nozzle and tube in spite of the air-pressure and in yielding thereto flow irregularly. To remedy this, we provide the machine 1n some cases with a positive feed mechanism, consisting, as herein shown, of a worm-chamber and a worm interposed between the discharge-orifice of the tank and the tube 66, Which delivers the compound onto the surface of the ball. Where this mechanismis designedto be interchangeably used, it is referab y interposed in an transversely o the discharge-spout 64, constituting, in effect, a part thereof, as shown in Fig. 1, so that the l simple'discharge-nozzle shown in Fig. 2 can be removed and the positive feed-discharge nozzle shown in Fig. 1 substituted, and vice versa, according as the 'character ofthecomound does or does not require the positive eedmechanism. In machines designed to" use only a thick and irre `larly-iiowing compound such positive fee mechanism instead of constituting a part of a removable discharge-spout may be made a permanent part of the machine and disposed beneath the tank in the manner indicated in the detail v views, Figs. 1 1 and 12, Whichlatter views illusbly mounted a shaft 60h, on which, Within the chamber, is iixedly mounted a Worm-spiral The receiving end of the worm communicates through a duct or assage-way 60CI through the wall of the chamber and the parts connecting the same to the tank 60 with the interior of the latter, and through a port 60", controlled by a stop-cock 6()f at the opposite or' discharging end of the chamber, wlth the tube 66. The shaft 60b is driven from a pulley 60g, Fig. 1, on the main drivin shaft 10, through a belt 60h,I engaging the pu ley 60i on the shaft 60h. The worm-shaft 60b is illustrated as jointed at 60k in Fig. 12, Where it passes through'the removable head of the hcas- .1ng 60a', such a constructionbeing a plicable where aseries ofv worms are place on the shaft 601? or any extension thereof and-are run' from the single drivingfpulley- 60g on the main drlvlng-,shaft '10, the tongue-joint 60k sance worms singly when desirable or necessary for 6 5 'purposes of cleaning or repair.

The compound which is fed from the tank 60 is of a gummy nature, and consequently tends to adhere to the teeth of the disks. The evaporation of the vehicle from the compound which adheres to the disks leaves the compound tough and unfit to enter into the Wall of the ball in that condition, as it would be in lumps and shreds. It therefore becomes necessary to remove it before it can adhere'to the ball. This compound is easily stripped or picked from the disks as the vehicle leaves it, which is very quickly, and We have, found that it itself in the form of a ball constitutes an eX- cellent means for cleaning the later accumulations from the disks. g ably use a mass of this rubber compound in the form of a ball (designated by as the cleaner-ball, which ball may be coniinedin an inclined trough 76 in such a manner as to -cause it to be tumbled by the rotation of the disks engaging the same in opposition to the action of gravity tending to maintain the bag in contact 1tlheiewith, the ball an stripping t e rying compoun forms in a toughening film from the disks, these additions thus becoming a part of the cleaner-ball, which may be removed to be ltrimmed down, being replaced by another meanwhile When' it has become by accumulation too larg'e or irregular.

It will be herel stated that while the mech-l anism already shown and described for mounting the calipers 30 and the catch-openating mechanism is perfectly satisfactoryr We sometimes prefer to employ other mec an- We therefore preferism, which is illustrated. in detail in Figs. 7 8, and 9 of the drawings, wherein the parts already described and their reference-numerals are repeated in order that the operation of this modification of our device may be more fully understood. Referrin thereto, 77 designates an axially-cored bloc or collary coniinedbetween thelower face of the block 77 and the'adjustingnut 35 on thelowerfend thereof. The caliper-arms 30' are pivoted 'upon the threaded boss79, being confined thereon, but with freedom ofpivotal 'movement bya nut 80. The rear ends of the cali per arms are aperture'd to receive the notched shorter Amember of the tripper and to co erate therewith in actuatirg the lever 36 in t l`e manner already describ The opera-tion of the machine will bfc fairly i evident from the foregoing description of its construction and co eratin parts, but may be brieiiy eXplaine as fo ows Assuming that it is to be employed in winding alayer constituting a part of the body portion of a sition thereupon. A nucleus or core for the -ball to be wound is then laid upon the periphery of the winding and tumbling disks 12`between the caliper-blades in the relative posi-l tions shown in the drawings, the thread from the spool 44 having been previously carried up over and through its guides and tension and given a few turnsby hand around the core or nucleus to connect it with the latter.l The handle 17 is then turned upwardly vfrom the horizontal to the inclined.V position, which automatically sets the catch mechanism to the position shown in Fig. 4, at the same time raising the tripper-32 and permitting the caliper-blades 31, under the action of the bow-.spring 42, to: ap roach the sides of the ball at diametricallly opposite onts thereof. against the torsional action of 'the spring 27- at the same time throws the two clutch members 23 and 24 into coperative engagement,

.thereby lsetting in rotation the winding and -tumbling disks 12. At the same time also the same rocking movement of the-shaft 15 v through the arm 74 closes the exhaust-'valve `I71 and opens the air-inlet valve 70,4 thereby ,permitting air-pressure to enter the upper portion of th'e tank 60 and exert a discharging effect upon the vupper surface of the material therein. As soon as the winding is thus far underway the cock or valve 65 is opened more or less, thereby permitting the semi- ,viscous .materialin the tank to ooze down through the nozzle and s out and distribute itself upon the threa or yarn as it is laid .upon the ball.

In machines em loying the described worm or other` feedmec anism of course the compound 1s positlvely fed inre ulated uanti- -ties to the surface ofthe bal ,-in whic connection itl may be noted that the ositive compound feed mechanism has anot er advantage 1n that anyvariation in the speed of the tumbllng-disks is accom anied by a like "variation in the speed of t e feed mechanism', thus rendering the amountof compound delivered upon' the -bally proportional to the amount or rate of'threa'd deposit or winding.4

- The. disks 12 'by virtue of their rotary movementobviously impart to the ball 47 a rapid ".-fv/llln'ing. movement .in an .opposite direction,` under"wh1cht h e thread or yarn is rapidly This elevation of the han le 17 'may be the ball -a practically universal tumbling.

movement, under which the yarn 'or thread is evenly and uniformly distributed thereupon e ball grows in diameter equally in all and t directions. As this growth proceed-s the cali er blades yand arms are gradually spread 4until when the ball has reached the predetermined size the caliper-arms have been spread to an extent just sufficient to bringV the apertures in their rear ends into perfect registration, thereby permitting the tripper 32 toy be drawn therethrough under the action of the spring 34. This tilts the lever 36 by a quick action, which releases the engagement of the counterweighted 'catch 40 wlth the end of the lever 36, thereby permitting the s ring 27 to exert itself, thus oscillating the shaft 15, throwing the catch mechansim to the position shown in Fig. 10, se arating the clutch members 23 and 24, there y stop#` ping the windin operation, andy opening valve 71 and closingy valve 70, thereby cuttin off the compressed-air supply to the tank an venting the latter of the pressure already existin therein. During the winding operation t e a plication of the adhesive material is -regu ated as desired bymeans of the cock. `or 60i controlling the lspout'64, whilel f-f the ball 75 automatically cleans the teeth of,

the winding and tumblin disks, maintaining f'- their action upon the bal uniform and eective. The automatic stopping of the machine notifies the attendant that the winding of the rvball is complete, whereupon the ball. 1s

removed, the broken end of the thread attached to a new core, the handle 17 raised, restorin the several'p'arts to operative position, an the described operation of the parts regeated. v n practice it will be found convementand economical where the exigencies of manufacture demand the service of a number of machines suchl as herein illustrated and described to group a plurality of such machines side by .side along and over the main longitudinal shaft 10,. In such case ,the machines may be arranged las closely together as they can be )conveniently operated, and various elements IIO thereof in addition to the driving-shaft 10-' such as thebrake-shaft 51, the support '59, the air reservoir or main, (not shown,)f&c.`-"

made common to the several machines. l l

While the automatic mechanism shown and described for gaging the ball andstopping the winding when the ball reaches'full .size constitutesja .valuable and important-f feature of the presentwmachine, yet 1t A1s fnotfi to be regarded as-arbsolutely essentialpartfi thereof, since We have foi-ind in practice that skilled Voperators learn to gage uickly with hand-cahpers the maximum iameter to WhichI the ball is to be Wound, and hence the automatic age and stop mechanism may sometimes he dispensed with. When such F is the case, the handle 17at the front of the machine attached to the rocking shaft 15,

that throws the disk-clutch into ear, is manually manipulated not only for t at purpose, but also in the reverse direction to se arate the. clutch and throw the Winding an tumbling disks out 'of gear. In such case the'hanthe particular forms herein shown and de'- dle is provided with a simple form of springcatch (not shown) for holding it in either position.

It is obvious that changes in the ydetails of the mechanism hereinabove described might be made Without aiiecting or departing from .the rinciple of operation ofthe machine, and We o not, therefore, limit our invention to scribed except to the extent indicated in -specific claims.
